System and method for controlling a service to use a resource

Abstract

A system for controlling a service to use a resource is disclosed. The system includes: an active bitmap obtaining module ( 21 ) for obtaining an active bitmap of the resource; an blacklist bitmap obtaining module ( 22 ) for obtaining a blacklist bitmap of the service; a checking module ( 23 ) for determining whether there is any service in the blacklist bitmap of the service which is also in the active bitmap of the resource; and a message returning module ( 24 ) for returning a message according to different results of the service using the resource. A related method is also disclosed.

1 . A system for controlling a service to use a resource, the system comprising: 
 an active bitmap obtaining module for obtaining an active bitmap of the resource, and releasing the active bitmap of the resource when the service finishes using the resource;    an blacklist bitmap obtaining module for obtaining a blacklist bitmap of the service, and releasing the blacklist bitmap of the service when the service finishes using the resource;    a checking module for determining whether there is any service in the blacklist bitmap of the service which is also in the active bitmap of the resource, and adding the service to the active bitmap of the resource if no such service exists; and    a message returning module for returning a message according to different results of the service using the resource.    
   
   
       2 . The system according to  claim 1 , wherein the active bitmap records at least one service which is using the resource currently.  
   
   
       3 . The system according to  claim 1 , wherein the blacklist bitmap records at least one service which cannot share the resource with the service when the service is using the resource.  
   
   
       4 . The system according to  claim 1 , wherein the message returning module returns a truth message when the service uses the resource successfully, or returns a false message when the service cannot use the resource.  
   
   
       5 . A method for controlling a service to use a resource, the method comprising the steps of: 
 starting the service;    obtaining an active bitmap of the resource;    obtaining a blacklist bitmap of the service;    determining whether there is any service in the blacklist bitmap which is also in the active bitmap;    adding the service to the active bitmap if no such service exists;    releasing the active bitmap and the blacklist bitmap; and    returning a truth message.    
   
   
       6 . The method according to  claim 5 , further comprises the step of: 
 returning a false message there is any service in the blacklist bitmap which is also in the active bitmap.    
   
   
       7 . The method according to  claim 5 , wherein the active bitmap records at least one service which is using the resource currently.  
   
   
       8 . The method according to  claim 5 , wherein the blacklist bitmap records at least one service which cannot share the resource with the service when the service is using the resource.
